OK, but not going to be as funny now (if it was ever going to be).
First, you must do all the normal stuff, well-drained area, fabric, cage, screen, etc.
Second, start with a pile of soil classified as USDA Prime Farmland. Sharon silt-loam association works for me.
Third, place said soil into temperate S.IL. Zone 6b.
Fourth, make a deal with the weatherman. Here's what I got for precip last year.
Check out that July-August-September rain!!!!
That's it, pretty simple. Almost guaranteed success for first year in the ground trees!!
I really do appreciate what some of you cold-weather guys have to go through to get trees to grow. I know I'm extremely blessed with what I have. That rainfall though, can't count on that again for sure!!
